I'll start out on subject matter. Macro yes...puzzle not so much. At just a glance I can tell that this is a flower. Granted. I couldn't identify what flower. I am sure that hurt your score some. As far as the shot itself, it's not bad. I think this works well as a b&w. I think that the crop should have been brought in slightly on the right. In the top right corner there is something that has kindof peeked into the frame that is a bit distracting. Otherwise good shot though
a lot of cockroaches?
a plant about to bloom?
I had a rather uncouth 3rd option that would likely get me blacklisted. if you're not afraid of being offended, msg me and i'll tell you in a PM.
giving this a 7 regardless
